From 7c5d62388e88729775b10a1748f2810e413f1e51 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 8 Nov 2012 07:58:53 +0100 Subject: [PATCH] mtip32xx: fix shift larger than type warning If we're building a 32-bit kernel and CONFIG_LBADF isn't set, sector_t is 32-bits wide. The shifts by 32 and 40 are thus larger than we support. Cast the sector offset to a u64 to avoid these warnings.
